Wrong mapping the cpu codename of Intel i7-8665UE processor

[Rex Tsai]

The checkbox report recognize Intel Core i7-8665UE as "Kaby Lake"[0], but it should be Whiskey Lake based on Intel ARK database[1].

It seems we have a wrong mapping in bin/inxi_snapshot[2].

% grep "kaby lake" attachment_files/com.canonical.certification__system_info_json
13: "Model: Intel Core i7-8665UE arch: Kaby Lake "

[1] Whiskey Lake - https://ark.intel.com/content/www/us/en/ark/products/193554/intel-core-i7-8665ue-processor-8m-cache-up-to-4-40-ghz.html

FYI bin/cpuid.py in checkbox also does this by getting the CPUID return from the processor and checking the ID string to determine the CPU family.

I do not add much desktop CPUs, and currently it only has AMD and Intel CPUs, but feel free to add to it.

Interestingly, inxi_snapshot does not recognize my i7 as Skylake...

@Jeff even with ./inxi_snapshot -C -xx ??

Inxi snapshot is https://github.com/smxi/inxi/blob/1639125a176cd56aa913937b59b8bed48749f7c2/inxi :

my $self_version='3.0.27';
my $self_date='2018-10-14';

We could evaluate a refresh of it from master:

my $self_version='3.3.04';
my $self_date='2021-04-16';

Two jobs are currently depending on inxi:
- system-info-json
- raw_device_dmi (to get bios mode info - legacy or uefi)

Eh... I wish I was able to follow up on this but my skylake MB died and I ended up having to upgrade the whole thing to a newer Comet Lake CPU/MB.

But on that one... I get N/A for arch:
bladernr@galactica:~/development/plainbox-provider-checkbox/bin$ ./inxi_snapshot -C -xx

the latest inxi from github does identify my Comet Lake CPU:
bladernr@galactica:~/development/inxi$ ./inxi -C -xx

And also seems to have better differentiation between Kaby Lake, Coffee Lake, Comet Lake and Whiskey Lake

So just updating inxi should work then.
